How do you scale objects in MLCAD?

Select everything, then hit the "Enter position orientation" icon (keyboard looking one).
Check "use rotation matrix value", and change matrix 1 0 0 0 1 0 0 0 1 to <scalex> 0 0 0 <scaley> 0 0 0 <scalez>

And I need the height coordinates to be integers, not decimals. How do I accomplish this?

After scaling, you need to round everything to integers. I think the simplest is to open the file in LDDP. Change decimal accuracy to 0 (tools -> options -> configurations values tab -> editor behavior subtab -> position decimal accuracy = 0). Then select all (ctrl A) and round everything (ctrl D).

Edit: this changes to integers height AND x-z coordinates. I have to simple way to do that only on y.
